service the N5241AS and N5242AS Option H30 and H31 (IF Outputs) in the N5241/42AS PNA-X Microwave Network Analyzer. The Option H31 provides a wider IF bandwidth for the IF Outputs. The N5241/42AS is a N5242A PNA-X with custom options in addition to the standard options available. Refer to the standard N5242A User and Service Guide for further information. Description The N5241/42AS Option H30 and H31 provide IF Outputs on the rear panel and require Option 020 (External IF INPUTS) to verify the Option H30 and H31. This enables the PNA-X to be used as a downconverter. The Option H30 IF Outputs, A, B, C/R1, D/R2 and R are the result of the RF Input signal at the PNA-X test port, or RCVR IN mixing with the internal source. The R IF Output is only available on the 4-Port N5241/42AS Option H30. The Option H31 IF Outputs, A, B, C/R1 and D/R2 are direct from the mixer with an IF splitter/amplifier assembly installed to provide more gain and bandwidth over the RF frequency range of 3 to 300 MHz. R IF Output is not available with Option H31. The IF Outputs are terminated with a 50 Ohm load when not in use to reduce radiated emissions and protect the IF Outputs. 2 User’s and Service Guide N5242-90012 N5241/42AS Option H30/H31 Specifications Specifications Table 1 IF Output Characteristics Description 2-Port 4-Port Option H30 IF Output Characteristics Input Frequency Range 1 10 MHz to 26.5 GHz 10 MHz to 26.5 GHz Center IF Frequency Output2 PNA-X Freq − RF Input Freq + IF Offset = IF Freq Output PNA-X Freq − RF Input Freq + IF Offset = IF Freq Output IF Frequency Bandwidth 40 MHz max 40 MHz max IF Output (A, B, Conversion Loss) −13 dB (± 5 dB) −13 dB (± 5 dB) IF Output (C/R1, D/R2 Conversion loss) −25 dB (± 5 dB) −13 dB (± 5 dB) IF Output (REF) Conversion loss n/a −25 dB ((± 5 dB) Compression Input Level +10 dBm at 1 GHz RF Input +10 dBm at 1 GHz RF Input IF Output Impedance 50 Ohm 50 Ohm Option H31 IF Output Characteristics Input Frequency Range 10 MHz to 26.5 GHz 10 MHz to 26.5 GHz Center IF Frequency Output2 RF Input Freq + IF Offset − PNA-X Freq = IF Freq Output RF Input Freq + IF Offset − PNA-X Freq = IF Freq Output IF Frequency Bandwidth 3 dB, 200 MHz 6 dB, 300 MHz 3 dB, 200 MHz 6 dB, 300 MHz IF Output (A, B, Conversion Loss) −10 dB (± 5 dB) −10 dB (± 5 dB) IF Output (C/R1, D/R2 Conversion loss) −10 dB (± 5 dB) −10 dB (± 5 dB) Compression Input Level +10 dBm at 1 GHz RF Input +10 dBm at 1 GHz RF Input IF Output Impedance 50 Ohm 50 Ohm 1. The coupler in the test ports causes high conversion loss for frequency < 500 MHz. Use RCVR Input for best conversion loss. 2. Refer to Equation 1, “IF Offset Frequency” on Page 5.

The downconverted IF signals are the difference between the RF signal frequency at the test port you are using, and the tuned frequency of the PNA-X. The amplitude of the IF Output signals will increase or decrease if the RF Input signal amplitude changes. The IF Output frequency will increase or decrease with the input frequency applied to the test port or RCVR Input as shown in Equation 1. To simplify the equation set the IF Offset to a usable integer, for example 1 MHz IF would replace the default IF Offset (7.60563380282 MHz). Reference the following commands: 1. sens:if:freq 1e6 (sets the desired IF frequency, in this example 1 MHz) 2. sens:if:freq:auto off (activates the selected IF frequency) Equation 1 IF Offset Frequency IF = ( RFSignalFreq + IFOffset ) – PNAXFreq CAUTION Do not apply DC or RF on the IF Outputs, the IF Outputs are DC coupled. Typeface Key Conventions The following key conventions are used throughout this document. • [HARDKEYS] are labeled front panel keys • SOFTKEYS are unlabeled key whose function is indicated on the instrument display. User’s and Service Guide N5242-90012 5 N5241/42AS Option H30/H31 Operating the PNA-X as a Downconverter Downconverting the Signal Using a Test Port Port 1 can be used to downconvert an RF Input signal using the PNA-X. Selecting S12 will enable the RF applied signal at Port 1 to be downconverted to the IF Offset ± the difference of the RF signal and the tuned frequency of the PNA-X. Refer to Equation 1, “IF Offset Frequency” on Page 5. CAUTION Do not exceed the maximum input power of the test ports or RCVR Inputs, or damage to the PNA-X will occur. The maximum input power on the PNA-X test port is 30 dBm (1 W) or 40 VDC. 1. Connect the RF signal to be downconverted to Port 1. 2. Select [Sweep] > Sweep Type > CW Time. 3. Input the frequency desired to downconvert your RF signal. Note: The IF signal will decrease approximately 3 dB when your RF signal is 40 MHz more than the PNA-X frequency. Example: Select [Freq] > [1 GHz]. 4. Set the PNA-X to measure S12. Select [Meas] > S12. This will set Port 1 to be the receiver port and Port 2 will be a source port. 2-Port PNA-X • Port 1 — Set the PNA-X to measure S12. A and D/R2 IF Outputs will have the downconverted IF signal. • Port 2 — Set the PNA-X to measure S21. B and C/R1 IF Outputs will have the downconverted IF signal. • There will be no signal on the IF Output R in a 2-Port PNA-X. 4-Port PNA-X • Port 1 — Set the PNA-X to measure S12. A and R IF (Option H30 only) Outputs will have the downconverted IF signal. • Port 2 — Set the PNA-X to measure S21. B and R IF (Option H30 only) Outputs will have the downconverted IF signal. • Port 3 — Set the PNA-X to measure S31. C/R1 and R IF (Option H30 only) Outputs will have the downconverted IF signal. • Port 4 — Set the PNA-X to measure S41. D/R2 and R IF (Option H30 only) Outputs will have the downconverted IF signal. 6 User’s and Service Guide N5242-90012 N5241/42AS Option H30/H31 Performance Verification Downconverting the Signal Using a External Receiver Input The external RCVR Input (A, B, C or D) bypasses the internal test port coupler, resulting in less loss of the RF signal to be downconverted. It is recommended that you use the external RCVR for input frequency < 500 MHz. The coupler in the test ports causes high conversion loss for frequencies < 500 MHz. To use the receiver input, remove the jumper (RCVR IN to CPLR ARM) and connect the RF signal to the RCVR IN female SMA on the front panel. Removing the jumper will disable the front panel test port. CAUTION Ensure the receiver input power level is < +15 dBm with 0 VDC if you are using RCVR A, B,C or D IN or damage may occur. Performance Verification The operational check allows the user to verify the IF Outputs are functioning. The N5241/42AS Option H30 and H31 can be verified in two different ways. Connect the IF Outputs to the IF Inputs and verify the trace on the PNA-X, or measure the IF Output using a separate instrument such as a power meter or spectrum analyzer. IF Output Verification Using N5241/42AS Internal Receivers This procedure verifies the Option H30 and H31 IF Outputs using Option 020 (External IF Inputs) by connecting the IF Outputs to the IF Inputs. The IF Outputs will be measured by the internal N5241/42AS receivers. • A and C/R1 external IF Inputs measure B and D/R2 IF Outputs. • B and D/R2 external IF Inputs measure A and C/R1 IF Outputs. 1. Connect the cables from the IF Outputs to the IF Inputs on the rear panel, using four 1 foot SMA cables as shown in Table 3 (Agilent RF cable part number 5062-6662 or equivalent).

User’s and Service Guide N5242-90012 27 N5241/42AS Option H30/H31 Measuring the IF Outputs Figure 24 3 dB Bandwidth Figure 25 6 dB Bandwidth 28 User’s and Service Guide N5242-90012 N5241/42AS Option H30/H31 Theory of Operation Theory of Operation The N5241/42AS Option H30 provides IF Output connectors on the rear panel that connect from the IF Mux assembly (N5240-60045) IF Outputs A (P2), B (P202), C (P602), D (P802) and R (R402). The test port or external receiver input is downconverted to an IF frequency (Input Freq + IF Offset - PNA set frequency). Refer to Figure 26, “N5241/42AS Option H30 RF Block Diagram.” The N5241/42AS Option H31 provides IF Output connectors on the rear panel. The IF splitter/amplifier assemblies (N5242-63160) connect the receiver outputs A, B, C and D from the mix brick assembly (5087-7727) to the IF Output connectors on the rear panel. R1, R2, R3 and R4 signals are also routed through the IF splitter/amplifier assemblies providing signal conditioning to match receivers A, B, C and D, required for IF gain calibration to operate correctly. The N5241/42AS Option H31 provides a wider IF Output bandwidth than Option H30, by bypassing the IF Mux assembly filtering. The IF splitter/amplifier assembly splits the power of each IF path. The first assembly splits the 2-Port, or 4-Port PNA-X outputs (A, R1, B and R2) from the mixerbrick. A second assembly splits C, R3, D and R4 for a 4-Port PNA-X only. In addition the splitter/amplifier assemblies amplify the IF signals to correct for the loss of the splitter, and provides isolation for each path. An additional 5 dB of gain is provided for the rear panel IF Outputs. The IF signals are routed from the IF splitter/amplifier assembly to the IF Mux assembly (N5240-63045) Inputs A (P1), B (P201), C (601) and D(801), and to the rear panel A, B, C and D IF Outputs. The REF IF signals are routed to the IF Mux assembly Inputs R1 (411), R2 (412), R3 (413) and R4 (R414). A power supply ribbon cable from J111 on the IF Mux assembly provides DC +15 V for the IF splitter/amplifier assemblies.

User’s and Service Guide N5242-90012 41 N5241/42AS Option H30/H31 Electrostatic Discharge Protection Electrostatic Discharge Protection Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables to the instrument. Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged. Static discharges too small to be felt can cause permanent damage. To prevent damage to the instrument: • always have a grounded, conductive table mat (9300-0797) in front of your test equipment. • always wear a grounded wrist strap (9300-1367) with grounding cord (9300-0980), connected to a grounded conductive table mat, having a 1 MΩ resistor in series with it, when handling components and assemblies or when making connections. • always wear a heel strap (9300-1126) when working in an area with a conductive floor. If you are uncertain about the conductivity of your floor, wear a heel strap. • always ground yourself before you clean, inspect, or make a connection to a static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly. • always ground the center conductor of a test cable before making a connection to the analyzer test port or other static-sensitive device. This can be done as follows: 1. Connect a short (from your calibration kit) to one end of the cable to short the center conductor to the outer conductor. 2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector. 3. Connect the other end of the cable to the test port and remove the short from the cable.

Shipping Your Analyzer to Agilent for Service or Repair IMPORTANT Agilent Technologies reserves the right to reformat or replace the internal hard disk drive in your analyzer as part of its repair. This will erase all user information stored on the hard disk. It is imperative, therefore, that you make a backup copy of your critical test data located on the analyzer’s hard disk before shipping it to Agilent for repair. If you wish to send your instrument to Agilent Technologies for service or repair: • Include a complete description of the service requested or of the failure and a description of any failed test and any error message. • Ship the analyzer using the original or comparable antistatic packaging materials. • Contact Agilent for instructions on where to ship your analyzer.
